One object of this `invention is thelprovision of a simple store front construction, which can The inventionfurther contemplates a construction in which `the component elements are positively locked together and are releasable only from the rear thereof.

` Other objects and advantages of my invention will `become more apparent from the following detailed description.

`Certain embodiments of the invention `are `shown in the accompanying drawings, wherein:

Figures 3l and 4 are, respectively, isometric views of a sash bar Vand a cover joined by an obliquely disposed web 9.

`wardly projecting flange I6 is formed along the plate, constituting parts of the construction. Figures 5, 6l and '7 vare isometric views of various styles ofsupporting blocks for the glass` plate. Figure vistan isometricview of a spring clip especially adapted for positioning the block shown in Figure '7.` `Figures 9, l0 and 11 are vertical sectional Views of additional embodiments of the invention.

`Referring to the drawings, a sash frame or easement `I of the usual wood construction is rabbeted along itsouter edge to provide a groove 2 and is covered with a metal plate or sheathing attached thereto by `means of countersunk screws `ispaced at suitable intervals. The casement I serves `as aseat for the sash construction 5, which is securedA therein.

` `The construction 5 comprises a sash bart, preferably of `extruded aluminum' or `other suitable a"`horizontal `baseV strip 8, the two strips being A forupper edge of the back strip l and is provided along its forward edge with a downwardly extending locking lip II comprising an upper portionyIZ anda lower portion I3 rearwardly offset therefrom and connected thereto by an obliquely extending web I4. 1 The lip II extends almost to 1 :the base strip 8 andthe portion I3 is provided with spaced notches .|5, the function of which willbedescribedlater. `The sash bar 6 is secured to the! casement Ibyany.` suitable means, as' for Il provided therein.

Blocks I9 for supporting a plate 26 of glass are positioned along the base strip 8 within the notches I5 provided in the portion I3 of the lip I I, as shown in Figure 5. The blocks I9 may be entirely of leather or other resilient and pliable material or,-as shown in Figuredthey may have a base 2|.of metal to which is attachedby means of countersunk rivets 22 a layer 23 of resilient material `which projects beyond the ends of the base 2|. Slots 24 are provided in the block I9 or resilient layer 23 to receive the section I3 ofthe lip II, the inherent pliabilityV of the material `in comprise an intermediate portion 28 reflexly bent i at Vthe ends to provide lugs 29 which engage the rear face of the section I3. The clip is bent forwardly from the lugs 2S to provide shoulders 36 that engage the ends of the base 25, and again reflexly bent inwardly to provide a second set of lugs 3l that engage the forward face of the block. From the lugs 3|, the clip is bent obliquely and rearwardly to engage the forward face of the lip section I3, thus locking the clip and block in position into the notch I5. The resiliency of the clip 2l is suiiicient to permit it to be bent slightly as itis'being inserted or removed from the notch I5 without entailing permanent distortion.

` The glass plate 20, the inner surface of which rests against the upper portion I2 of the lip II carried by the ange I6 of the sash bar 6, is held in position by means of a cover plate 32, shown in Figure 4. The cover plate 32, preferably formed of extruded aluminum in any desirable cross-sectional outline, is provided with a downwardly extending rib 33, which engages the outer surface of the glass plate 20, and an inwardly projecting ange 34 having spaced notches .35 positioned therein to receive `the supporting blocks I9. The flange 36 slidingly engages the base strip B of the sash bar 6 and the upper surface of the flange .has serrulations 36 engaging the lower edge `oi the locking lip I I. Screws 3l passing` through openings 38 project throughthe flange .I0 andthe base stript` of tbesash bart into the Casement and permit regulation of the pressure exerted by the locking lip II upon the flange 34 and insure a positive locking of the cover plate 32 in the construction. The screws 31 may be loosened to permit the construction to be dismantled, when such action becomes necessary.

In the modification, illustrated in Figure 9, the base strip 40 of the sash bar 4I, corresponding to the sash bar 6, is provided with a plurality of pockets 42 which receive heads 43 of bolts 44 extending upwardly therefrom through the flange Il). The tension exerted by the locking lip il is obtained by nuts 45 secured to the bolts 44. The nuts 45 may be loosened to permit the construction to be dismantled.

The modification of my invention as illustrated in Figure 10 is substantially the same as that illustrated in Figures 1 and 2, with the exception that the locking means are not integral with the ange of the sash bar. The sash bar 6 is provided with a flange 43, corresponding to the flange l5 in Figure 1, which carries along its edge a reflexly bent lip 49, forming a downwardly opening channel 50. The forward face of the lip 49 engages the inner surface of the glass plate 29 and the channel 56 provides a bearing for the upper edge of a locking plate 5l. The plate 5i is provided with openings 52 having tubular flanges 53 disposed thereabout. The enlarged cylindrical heads 54 of screws 55 extend within the flanges 53 and helical springs 56 disposed about the flanges 53 and the screw heads 54 maintain a positive outward pressure upon the plate 5| In this way the plate 5l is brought into engagement with the flange 34 of the cover plate 32. When it becomes desirable or neces- ,sary to remove the cover plate 32, the flange 48 may be lifted by means of any convenient instrumentality inserted throu-gh openings (not shown) in the flange to relieve the pressure exerted by the locking plate 5i against the flange 34, thus permitting the cover plate 32 to be moved away from the glass plate 20.

A further modified construction is illustrated in Figure 11, wherein a flange 653, corresponding to the flange 48, is provided at its forward edge with a downwardly extending lip 6i which engages the rear face of the glass plate 2li. The flange 34 of the cover plate 32 is locked in position by means of springs 62 substantially of inverted V-shape. One branch 53 of the spring is secured against the vertical back strip l of the sash bar 6 by means of a screw E4. The apex of the spring 62 rests in the angle betweenthe flange 60 and the lip 6l and the second branch 65 of the spring extends downwardlyinto engagement with the flange 34.

The mode of operation and the advantages of these constructions will be readily apparent to those skilled in the art. In the embodiment shown in Figures l and 2, the sash bar ii is placed around the Casement l, the supporting blocks i9 are mounted in the sash bar and the glass plate 20 is positioned thereon. The assembly is completed by sliding the cover plate 32 into position. The looking lip il is so constructed that it will allow the ange 34 of the cover plate 32 to be advanced inwardly, but at the same time it resists any outward movement. After the cover plate 32 has been installed, the screws 37 are tightened to exert additional force upon the locking lip Il, which in turn is communicated to the flange 34 to clamp the latterV against the base strip 8 of the sash bar. The modified construction shown in Figure 9 is assembled in the same manner, the component elements being locked together by the bolts 44 and the nuts 45 increasing the force exerted by the lip I I on the flange 34.

Operation of the embodiments of the invention shown in Figures 10 and 11 is essentially the same as that shown in Figures 1, 2 and 9. The spring actuated plate 5I or the springs 62 simply replace the locking lip Il.

In the foregoing constructions the sash bars and cover plates act directly as gripping means for the plates of glass. The inherent resiliency of the various parts and notably the flanges I0, 48 and Ell is sufficient to permit adjustments to various strains which may arise. Accordingly, the component elements will not be permanently distorted nor will there be a loss of the gripping action upon the glass.

It is to be understood that various changes in the shape, size and arrangements of parts as set forth in the form of the invention herewith shown and described may be resorted to without departing, from the spirit of the invention or the scope of the appended claims.
